Now that I have told you not to carry over yesterday's hurt feelings or annoyances, today I want to tell you that this doesn't mean you must continue every relationship or every dealing with a business or anything. Let Us say that a salesperson in a certain store was inconsiderate or rude to you, and you are not happy to go there anymore. You don't want to harbor a sense of the rudeness and hold a grudge, yet you are also free not to return to the store. You don't want to make a big deal of anyone's inconsiderateness, yet maybe that store is not the right place for you.
The language you use matters. Language is only language, yet your choice of words matters. How you speak bespeaks your relationship to the world. How you speak bespeaks how you think the world relates to you.
I would suggest that you favor gentle speech. That may help to tame the world and yourself.
At the same time as I say this, your speech is more than your words and tone of voice. Your speech is a revealer. It reveals your consciousness.
